我正在尝试将这个问题的输出存储在 mysql 中

根据大小过滤网页中的图像

<?php 

include('connect.php'); 

$html = file_get_contents("http://santabanta.com/photos/amisha-patel/402186.htm"); 

$doc = new DOMDocument();
@$doc->loadHTML($html);

$tags = $doc->getElementsByTagName('img'); 

foreach ($tags as $tag) { 
    $data = get_headers($tag->getAttribute('src'),1); 
    if((intval($data["Content-Length"])/1024)>=10){ 
        echo $tag->getAttribute('src');
        $url=''.$tag->getAttribute('src').'';
        echo $url;
        mysql_query ("INSERT INTO table1 (url) VALUES ('" . mysql_real_escape_string($url) . "')");
    }
} 

?>

但令我惊讶的是，只存储了输出的第一个链接/链接。我已经使用 echo 进行检查，并且 echo 给出了正确的输出。

我用于存储此代码的 mysql 数据类型是文本，我正在使用此 mysql 查询插入 mysql 但只保存第一行。

mysql_query ("INSERT INTO tablea (url) VALUES ('" . mysql_real_escape_string($url) . "')");

从 echo 获取结果时一切似乎都很好，但后来它没有存储在 mysql 中。

我试图在表单字段中填写这些回显详细信息，令我惊讶的是，只有第一行也填写了表单字段，所以无论 mysql 存储什么都是按照表单字段输出，我只是试图检查它的 mysql 问题还是什么。我直接在 phpmyadmin 中执行了查询，所有内容都被存储了，但是通过表单它没有得到但是 echo 给出了完整的细节。

这是我使用的代码

<?php 

include('connect.php'); 

$html = file_get_contents("http://santabanta.com/photos/amisha-patel/402186.htm"); 

$doc = new DOMDocument();
@$doc->loadHTML($html);

$tags = $doc->getElementsByTagName('img'); 

foreach ($tags as $tag) { 
    $data = get_headers($tag->getAttribute('src'),1); 
    $filesize = (intval($data["Content-Length"])/1024);
    // Modify the integer below to what size KB you want.
    if($filesize >= 10){ 
        //echo $tag->getAttribute('src');
        $url = $tag->getAttribute('src');
        // Do the insert here so it enters if all criteria are met.
        $query = "INSERT INTO tablea (url) VALUES ('" . mysql_real_escape_string($url) . "')";
        $result = mysql_query($query);
        // This to check what the error may be and your insert statement.
        if(!$result) echo mysql_error() . " | " . $query . "<br />";
    } else {
        echo "File not added: ".$tag->getAttribute('src')." | " .$filesize. "kb<br />";
    }
}

?>

我的结果如下：

由于文件不符合条件，因此不会添加它们。这次只有两个图像添加到数据库中。
